Additional cables at each end of the platforms are each secured at the lower end to the lowest platform and pass through guides secured to the intermediate and top platforms to a winch enabling the platform to be quickly lifted and stacked but allowing them to be quickly lowered and erected. The guides provide lateral location of the stacked platforms.
